Retrofit Services

Attendance  onboard the vessel during dry docking or when in port, to investigate feasibility of installation of the ERMA FIRST Ballast Water Treatment System (BWTS). All necessary areas are scanned with a 3D Laser scanner and the generated point cloud used to evaluate/verify the different installation layouts.

After completion of scanning, 3D modeling of the main piping s performed. The 3D modelling is reviewed by using the output of the 3D scans of the areas chosen for new equipment components’ installation to evaluate their preliminary arrangement feasibility. These feasibility study results are taken into consideration for the selection of the system. Installation will be further studied.

Performance of an engineering study for BWTS installation, based on available documentation and onboard survey results, including complete proposal with ballast water treatment system modelling, routing of piping (including piping isometric drawings, materials and parts list), specification of structure and outfitting modifications and Class required drawings. Preparation of all necessary modifications of the “as built” drawings (structural, piping, outfitting, electrical).

Preparation of the required drawings, which will are submitted to vessel’s Classification Society and/or Flag State as necessary, for approval. Preparation of technical specification of modification/retrofitting, in order to be submitted to various shipyards or repair facilities for receiving quotations.

Estimated Time of Delivery: 20 weeks after completion of the survey on board. Attendance onboard lasts one day.

Deliverables: A report with the survey findings in electronic format. All 3D scan files will be given to the Client. A detailed report with the preliminary arrangement for the BWTS, including 3D model of the equipment, the basic piping systems and their location in the point cloud created after 3D Laser Scanning, for reference, followed by a detailed report of the study’s outcome and a presentation at the Client’s premises or a teleconference (at Client’s discretion) will be this project’s deliverables. 

The deliverable engineering study file include: 

• Isometric piping drawings (with materials and parts list) 
• Detailed piping sections/spools 
• Modifications of the affected “as built” structural, outfitting, diagrammatic piping and single line electrical drawings 
• Class approved drawings 
• Technical specification of installation and related modification works 

ERMA FIRST is committed to work closely with the Classification Society, with absolute confidentiality and continuous communication of information.
